GMC adds stylish new Elevation model to 2019 Sierra lineup

GMC has announced a new style-forward model for its forthcoming 2019 Sierra pickup. It's called the Elevation and it will be based off the Sierra double-cab model with a new turbocharged engine, aimed at buyers who want a little panache with their rugged capability. GMC marketing director Rich Latek says the Elevation "conveys a youthful, athletic presence" with the pickup's chiseled fenders and assertive, upright hood. As such, the Elevation gets body-color-matching door handles, bumpers and grille surround, plus black exterior accents like the grille insert, tow hooks, side window trim and standard 20-inch aluminum wheels. Headlights, tail lights and fog lamps will be given the LED treatment, with the former getting the new C-shaped designs that have already been unveiled on other trim levels. It will be offered in two- or four-wheel-drive configurations, with nearly 3 inches more leg room than the current model. A traction select system will use a dial that drivers can set to preset driving modes to adjust transmission shift points, throttle mapping and other systems. An X31 Off Road package will be offered and boasts tuned suspension, a locking rear differential, protective skidplates, dual exhaust and other features. Also available will be a ProGrade Trailering System that includes a Trailering App to help connect and tow a trailer, on top of additional tie-down points, enhanced cargo lighting and other perks for hauling camping or recreational gear. Inside will be a standard 8-inch infotainment system compatible with Android Auto and Apple CarPlay with a six-speaker audio system, plus USB Type A and Type C ports for charging mobile devices. As for the powertrain, it will come with an all-new 2.7-liter turbo inline-four engine that makes 310 horsepower and 348 pound-feet of torque paired with an eight-speed automatic transmission. Also available is a 5.3-liter V8 that uses a new efficient fuel management system that enables it to operate on anywhere from one to all eight cylinders, depending on demand. In early 2019, a new 3.0-liter turbo-diesel inline-six will also be offered, mated to a 10-speed automatic. The Elevation adds to Sierra models like the SLT and Denali that GMC unveiled earlier this year. The company has shaved as much as 360 pounds off the new 2019 model — plus more from the Denali, thanks to carbon fiber in the bed box — so fuel economy should see a boost, too. It goes on sale in the fall.

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.
